Acrylic 8% spun silk mixed yarn fiber has thermal extensibility and is suitable for making bulked yarn, wool, knitted fabric and artificial fur. After the performance of acrylic fiber, it feels soft, easy to dye and bright in color. The elasticity is not as good as wool, polyester and other fibers, especially after repeated stretching, the remaining deformation is large. Therefore, the cuffs and necklines of clothes made of acrylic fiber are easy to deform. The hygroscopicity of acrylic fiber is lower than that of nylon, and it is prone to static electricity and pilling. Acrylic fiber has low thermal conductivity and light texture, so it has good warmth retention. At the same time, it has sunlight resistance, insect and mold resistance, and is widely used in knitted clothing. It can be dyed with disperse dyes, cationic dyes and acid dyes. It is formed by merging and twisting two or more strands. Use more than two yarns of different thicknesses, different materials, different structures or different colors to twist and combine, or use special methods to twist and make strands of special shapes or structures.
There are many types of fancy threads, and they emerge in endlessly with the development of new technologies. If there are knot lines, spiral lines, circle lines, colored dot lines, etc. Fibers are formed from straightening to crimping under the action of heat and machinery, or under the action of high-pressure jets of air. The undeformed synthetic filament has a smooth, straight, non-bulky appearance and no feathers on the surface. After texturing, the yarn is crimped and bulky, with feathers on the surface, soft to the touch, soft luster, and improved wearability such as moisture absorption, air permeability, and warmth retention. Textured yarns include stretch yarns, low stretch yarns and bulky textured yarns. Wrapped by core yarn and outer yarn. The core yarn is in the center of the yarn and is usually a strong and elastic synthetic filament (polyester, nylon, spandex, etc.). Fire-retardant acrylic fiber is a functional fiber with fire-retardant properties developed after flame-retardant acrylic fiber. It is widely used in clothing, home furnishing, decoration, non-woven fabrics and fillers.
Through the pretreatment of this raw material, various processes and the temperature and humidity of the production process workshop, our company has carried out technical research and adjustments, and solved a series of bottlenecks restricting the normal production. The fireproof acrylic yarn was successfully spun, and the quality of the yarn was obtained. Customer recognition. The average length of the fireproof acrylic fiber is 51mm, but there are 70-80mm long fibers, the fineness is 1.1dtex, the breaking strength is 2.59cN/dtex, and the elongation is 20.1%. Compared with ordinary acrylic fiber, the strength and elongation are reduced to varying degrees. Use rubber rollers suitable for spinning chemical fibers with good anti-winding performance, and supply the eye numbers of the draw frame according to the barrel number during the operation.
The machine adopts isolation and humidification. When changing the cylinder before the machine, place the plastic bag in a proper lowering, and the speed of the needle roller is reduced from .Acrylic fiber properties and use.It has better elasticity, second only to polyester, and about 2 times higher than nylon. Has good shape retention. Strength: Although the strength of acrylic fiber is not as good as polyester and nylon, it is 1 to 2.5 times higher than wool. Heat resistance. The temperature of the fiber is 190-230C, second only to polyester in synthetic fibers. Light resistance: The light resistance of acrylic fiber is a good one of all synthetic fibers in the open air, and the strength is only reduced by 20%. Acrylic fiber is resistant to acids, oxidants and general solvents, but not alkali. Acrylic finished products have good bulkiness, good warmth retention, soft hand feeling, good weather resistance, mildew and moth resistance. The warmth retention of acrylic fiber is about 15% higher than that of wool.
